To all whom it may concern:

Beit known that I, LAFAYE'IT L.. BAENETT, a c1t1zen of the United States, residing' at Canton, in the county of Lewis and State of Missouri, have invented certain new and useful Improvements in PickleGrading Machines; and I do hereby declare the followving to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for grading pickles and other similar material whlch can be graded according to size; and` frame in a substantially horizontal position by means of pivoted hangers c', which permit it to oscillate longitudinally. This screen is provided with a series ofbars or screening-iingers c'. These bars vary in width -step by step, and are widest under the 'hopper B. The'portions .fof the bars which extend under the hopper are not intended however to screen the pickles. j

D are spacing bars carried by the Jframe A and provided-with Oblong holes d. Bolts d provided with nuts for securing them to the bars are adjustable in the slots d laterally ofthe screen bars, andthe lower ends of these bolts are secured to the bars D at suitable intervals in order to support the bars and hold them at the desired distances apart'from each other.

E is the driving-shaft of the machine j ournaled 'in bearings e secured to the other end of the frame from the hopper. The shaft E is provided with a driving-pulley and fly-wheel e', and it' has at its middle part a crank f.

F is a connecting-rod between the crank f and the screen C, so that the said screen is reciprocated lon itudinally `when the driving-shaft is revo ved.

A shaft Gr is journaled in suitable bear ings on the frame in front of and below the j `driving-shaft LE, and is provided with wheels g. Endless flexible connections H pass over the wheels g and'over similar wheels h on a Vshaft `at the `front end of the machine.

The iiexible .connections H can he chains,

cords or any other equivalent devices. Crossslats I are secured to the endless .fiexihle connections H, and are provided with agitating fingers z' having round heads z". The fingers z' are formed of straight metallic pins anv their heads are substantially spherical so that they projectaround the pins in all directions. The round heads of these fingers project upwardly from between the bars of the screen.

A s rocket-whee shaft and is driven from a sprocket-wheel 7c secured on the shaft E by means of a drive-chain le.

L is a brush which forms the rear end portion Vof the hopper, and which is adjustable vertically in the frame A, and secured in any desired position by means of any suitable fastening devices b1.

M are vertical partitions under the screen which form a series of compartments. These compartments are made to correspond in tions of the bars of the screen, and they form receptacles for the various grades of pickles. The compartments preferably have their bottoms formed of slats m, and boxes or cans may bc slid into the compartments to receive the pickles.

N are endless conveyers mounted on rollers n. andy n', and extending between the partitions below the screen, and workin cross-V wise of the screen. The rollers 'n an n are lmounted in suitable bea-rings on the frame A, and the driving-roller n, has a spiral toothed wheel p secured on its shaft. This Wheel p gears lnto a similar s iral toothed wheel p secured on the shaft so that the conveyers N are driven continuously. These conveyers N mayhowever be dispensed with, if desired.

Ris a table hinged to the frame below the delivery ends of the conveyers N, and affording a support for cans or boxes into which the graded pickles are discharged by the conveyers.

The pickles are placed .in the hopper and are fed out of it, under the adjustable brush, by the agitating fingers i which project, from the longitudinal conveyer, between the bars of the screen, and which cause the K is secured on the position and number with the stepped por:

pickles to traverse the said screen longitudinally. The small pickles fall through the' screen Vnear the hopper where the screen bars are Wide,a1id the various grades offpickles fall through the screenat differentparts ofy its length according to the distance between its bars. The round heads of the fingers prevent the pickles from being defaced, and together With 4the motion ofthe screen move the'pickles along and turn themab'out in a manner which insures their-being sepa-ratedv Y into the desired grades.

What I claim is:

In a grading machine, the combination,

with a screenhaving longitudinal bars of different widths at different parts of their length and arranged in the formof steps, of an endless conveyer provided :With lingers which project between the screen bars and which move the material longitudinally over the said bars, partitions arranged crosswise under the said screen and forming a series of compartments for the different grades of material, endless conveyei's arranged in the said compartments between the stretches of the aforesaid conveyer and discharging the materia-latone side of the machine, and driving mechanism foroperating all the said Veonveyers simultaneously.'

In testimony whereof I have affixed my signature 1n the presence of two witnesses.
